FLUSH-TANK.

SPECIFICATION forming part of Letters Patent No. 581,361, dated April 27, 1897. Application filed October 5,1896. Serial No. 607,855. (No model.)

T or whom it may concern:

Beit known that I, MARK O. MO0RE,of Hamilton, Butler county, Ohio, have invented certain new and useful Improvements in Flush- Tanks, of which the following is a specification.

This invent-ion pertains to automaticallyflushing tanks; and my improvements will be readily understood from the following desoription, taken in connection with the accompanying drawings, in which Figure 1 is a vertical section of a flush-tank exemplifying my invention; Fig. 2, a plan of a portion of the top bridge thereof with the float-stem and the wiper carried by it, and Fig. 3 a plan of the valve-controlling lever and its immediate accessories.

In the drawings, 1 indicates the tank; 2, the flush-valve; 3, the supply-cock; 4, a top bridge on the tank; 5, a float; 6, the floatstem projecting up through the top bridge; 7, a stop to limit the descent of the float; 8, a substantially horizontal lever mounted on a horizontal pivot on the top bridge; 9, a rod connecting this lever with the flush-valve, s0

. that the oscillations of the lever open and close the valve; 10, an adjustable weight on the lever to counterbalance the flush-valve and to give aid in an adjustable degree to the lever in opening the valve; 11, a stop to limit the degree of opening of the flush-valve; 12, a trigger engaging under the outer portion of the lever when the lever is in position corresponding with the closed condition of the flush-valve, this trigger having a counterweight tending to draw and hold it to engaging position, the trigger having an arm projecting up above the lever; 13, asimilar trigger at the inner end of the lever, this trigger serving to lock the lever in position corresponding with the open condition of the flushvalve; 14, a roller-weight traveling on the lever as a track and adapted to roll from one side to the other of the lever-pivot and to come against and disengage one or the other of the triggers; 15, an inclined wiper carried by the float-stem and engaging the trunnion of the roller and adapted, as the float-stem rises and falls, to move the roller outwardly and inwardly on the lever; 16, a clamp uniting the wiper adjustably to the float-stem,

and 17 an adjustable projection inwardly from the arm of trigger 12 toward the roller and serving to cause the roller to operate trigger 12 earlier or later in its approach to that trigger.

Supply-cock 3 remains always open the desired and adjustable degree, so that supplywater is always flowing into the tank at proper rate. As seen in Fig. 1, the flush-valve is closed and held closed by trigger 12. The

float rises as the tank fills, and wiper 15 moves the weighted roller outwardly on the lever. When the roller shall have passed outwardly beyond the lever-pivot, then the weight of the roller tends to depress the lever and open the valve, but trigger 12 prevents. When the roller shall have moved so far outwardly as to engage projection 17 and push trigger 12 outwardly, then the lever will be free of this trigger, and the flush-valve will be promptly opened by the action of weight 10 and rollerweight 14. Projection 17 is to be so adjusted that the trigger will be released and the flush valve thus opened when the tank contains the desired quantity of water for a flushing. When the lever has thus rocked and the flushvalve been opened, trigger 13 goes into action and locks the parts with the valve in open condition. The water now flows from the tank through the open flush-valve, and the float descends, the wiper carrying the roller inwardly up the reversely-inclined lever till the roller engages trigger 13 and unlatches it, the weight of the roller now closing the valve, trigger 12 looking the lever, the tank now again refilling, and so on.

The quantity of water discharged at each flushing can be adjusted at the projection 17, which determines at what stage in the filling of the tank the flush-valve shall be opened by the disengagement of trigger 12 under the influence of the roller. The frequency of the flushing is regulated at the supply-cock 3, whose rate of delivery determines the time taken in receiving that height of water adjusted for at the projection 17.

I claim as my invention- In a flushing-tank, the combination, substantially as set forth, of a tank having a dis charge and a supply, a flush-valve at the discharge, a substantially horizontal lever conneoted with the flush-Valve, triggers adapted with the float and adapted as the float rises to lock thellevei'finchpositions (gorrlespoinding and falls to move said Weight on said lever. alternative y Wi I e open an o ose posiit tion of the flush-valve, a Weight moving on MARK MOORE 5 said lever to one side and the other of its pivot Witnesses:
